Referring in detail to the'parts', I I designatesa base""m`mb'r to whichare' attached, by means ofsc'reivs' I2 arrdfII,- angular side"supportmern bers I 4'and':I5"respectively To the`said' 'sid'e membersthere "are attached' adjustable side isup'- pifi'f ImberS "l'ad IT'rs'ptve1y. Th Said adjustable sidejmfnbers I6 and Hare secured to thesaid' 'first menti'nedside support fniember's bytBesCreWs I8and'I9'respectivelywhich engage throughslots 20 and 2I andv provideameans forvertically adjusting the said adjustable side support membersVI s andV `I 1. A'ied'g 22 'is formed `uponeacliof the adjustable sidemembers IG'and I1 "and form `a 'track' upon'which carrier blocks 23 areadapted to move.

The carrier blocks v23 are formed with 'a central block 'formation 2 4having extending arms 25 and upwardly "extending end members`26-` Thece'ntrai' block"24"h'a`s` abore 2Iywhich functions as a bearingfor aroller shaft 4 28*carrying an impressinrouerzsr." The; upper @deesofthe" central ibis-ck; 2'4 ana 'upwa'rdiy'exfeaingena' porties-S 26 aregrooved as at 30 which engage downwardly turned lips 3I formed at topflange 32 of the adjustable side members I6 and I1. Upon the upper edge33 of each of the said side members I4 and I5 there is secured a rack34. The aforesaid imprinting roller 29 is carried upon the said shaft28, the ends of which extend through said bores 21 in the central blocks24 formed upon the said carrier blocks 23. Gears 35 are i-lxed upon thesaid shaft 28 and engage the said racks 34. Embracing the saidimprinting roller 29 and engaging the said shaft 28 is a rectangularshaped frame 36 having projecting ears 3'I and fingers 38 which supportsame upon said end members 26 formed upon said carrier blocks 24. Theends of the said shaft 28 extend through perforations in the sides ofsaid frame and into the said bores 21 which form bearing for same. Thegears 35 which are fixed upon the said shaft impart rotary motion to thesaid imprinting roller 29 when the frame 36, carrier block '23 andattached roller are moved along the said end members.

A handle 39 is attached to a yoke 40 which is in turn connected with thesaid frame 36. An end plate 4|, extending across one end of the basemember II, is secured to the ends of the angular side members I4 and I5by means of screws 42 and 43 and has upwardly projecting end portions 44and 45 which act as a stop means to limit the movement, in onedirection, of the frame 36 carrying the impression roller 29, itsattached gears 35 and carrier blocks 23. Upon the opposite ends f thesaid angular side members I4 and I5 there is attached by means of screws46 and 47 an end plate 48, similar to the end plate 4I but without theprojecting end portions 44 and 45.

A vertically adjustable bed member 49 is carried between the said sidemembers I4 and I5 and the end plates 4I and 48 and is adapted tovertical movement by means of the wedge blocks and 5I the Wedge blocks58 being Xed upon the under side of the said bed member 49 and the wedgeblocks 5I being connected to the bars 52 which terminate in a cross-bar53 which forms a handle for manipulating the Wedges 5I which are movableupon the base member II. Locking bolts or screws 54 attached to the saidadjustable bed member 49, engage through slots 55 in the end plates 4Iand 48 and provide means for locking the said bed member 49 in itsdesired position.

The said bed member 49 carries printing blocks 55, 56, 5l and 58(Figures 1 and 5) each of which comprises a partial design and is inkedwith a different color. The partial design of plate 55 is conventionallymarked for the color red, the partial design of plate 56 being markedfor the color blue, that of plate 51 is marked for brown and the plate58 marked for the color green.

The impression roller 29 is formed with a slot v59 into which one end ofa sheet of any suitable and register of each successive partial designas the printing roller passes over the printing plates.

In operation the various printing plates are inked with any desiredcolor, the sheet material attached to the roller and the roller drawnover the variously colored printing plates. As the roller passes overthe printing plates, the sheet upon the roller gets its first imprintfrom the plate 55, which in the drawings indicate the color red; thefollowing impression upon the sheet being blue from the plate 56 andnally green from the plate 58, giving the resultant composite designshown in Figure 6, where all the colors are imprinted to produce thecolored design shown. The sheet may then be removed and a new sheetplaced upon the roller and the operation repeated.

The bed member carrying the printing plates may be adjusted as, alreadydescribed, to conform to any varying thickness of sheet material. When aroller of larger or smaller circumference and its conforming gears areemployed, adjustment may be made through the medium of the adjustableside members.

The upwardly extending ends 26 of the carrier blocks 23 are providedwith lugs 65 having bores 66 within which pins 6l are secured. The saidpins carry cam elements 68 which are adapted to slidably engage alongthe upper edge 32 of the adjustable side members I6 and Il and areemployed to raise or lower the carrier blocks 23 and frame 36 withinwhich the roller 29 is mounted.

In Figures 7 and 8 the cam operation is diagrammatically shown. Figure 7shows the cam 68 in the position it occupies when the roller moves inthe direction shown by the arrow X. In such position the cam holds theroller in its lower printing position, while Figure 8 shows the positionof the cam when the roller is being retracted or moved in the directionindicated by the arrow Y. In this latter position the roller is slightlyraised to allow same to clear the printing frames while being retracted,

The printing plates .may be cut out of any suitable pliable materialsuch as rubber or linoleum or may be cut out of a metallic substancewhen required, and may be inked by hand after each operation.

While the drawings show four color printing plates, a greater or lessernumber `oi" printing plates may be used. Also the inking of the platescan readily be accomplished by the addition of automatically controlledinking rollers. Furthermore, the said impression roller may beautomatically operated by the addition of a motor and controls.

Other modications may be made without departing from the general spiritof the invention.

I claim:

1. An apparatus for printing multicolor designs upon sheet material,comprising a base member, angular supporting members attached to thesaid base member, vertically adjustable flanged members attached to thesaid angular supporting members, carrier blocks slidably mounted uponsaid adjustable flanged members, a shaft having end bearings in saidcarrier blocks, an impression roller upon the said shaft and adapted toturn therewith, gears upon the said shaft, racks upon the .upper edgesof said angular supporting members engaging said gears and adapted torotate said impression roller when said carrier blocks are moved alongthe said flanged supporting members, a frame encompassing saidimpression roller and slidably mounted upon said anged members, a yokedhandle member pivotally attached to said shaft and frame and providing ameans for manually moving the said frame and impression roller along thesaid anged supporting members, a vertically adjustable bed mountedbetween Said angular supporting members, multiple printing plates uponthe said adjustable bed, Wedge blocks secured to the underside of saidadjustable bed, complementary Wedge blocks slidable upon the said basemember and engaging said wedge blocks upon the underside of the saidadjustable bed, operating rods connecting the said complementary wedgeblocks and extending outwardly beyond one end of said adjustable bed, ahand hold connecting the outer ends of said operating rods providing ameans for operating the said complementary wedge blocks and -a platesecured at one end of the said angular supporting members adapted tostop the movement of the Y said carrier blocks.

2. An apparatus for printing multicolor designs upon sheet material asdefined in claim 1, including sliding cam elements upon the said carrierblocks engaging along the upper edge of said adjustable flanged membersand adapted to raise the said carrier blocks, frame and attachedimpression roller to clear the said multiple printing plates during theretractive movement of same.
